Question

What is the effect of shivering in raising the body temperature during cold weather?

• A. Shivering dilates blood vessels
• B. Shivering constricts blood vessels
• C. Shivering increases the heart rate
• D. Shivering stimulates rapid muscle action
• E. Shivering tightens skin to cause goose bumps

Answer 1

Answer: (D)

Shivering stimulates rapid muscle action

Our body needs to maintain a 37°C to function properly. If it drops it could damage our organs or brain, so to stop this happening, our body strictly regulates temperature. Shivering is an involuntary pattern of repetitive, rhythmic muscle contractions. This twitching exercise produces heat, which helps to raise body temperature. Thus, the correct answer is option D.
